1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

To manage the adverse effects of garbage pollution and avoid using chemicals, a natural extract of seafood shells was obtained and explored for its beneficial role. Physical characterization highlighted that its active compounds correspond to chitin and its derivative, chitosan. The ability of the extracted biostimulant to foster tomato tolerance was tested on drought-stressed plants. Along with changes in morphological parameters, the accumulation of chlorophyll and carotenoids was improved. The biostimulant also mediates the accumulation of osmoprotectants and an increased leaf water content. Furthermore, the biostimulant effectively promotes tolerance by increasing drought-stress SIERF84 Transcription factor and decreasing both SIARF4 and SlWRKY81 transcript levels, which in turn, mediates stomatal closure. In addition, the up-regulation of key genes related to NO
